Formaldehyde :: terrestrial ecosystems

Key Concerns:

Short-chain alcohols and aldehydes are produced and emitted by some plants. There is evidence that methanol applied to leaves may be beneficially metabolised. Biochemical pathways exist in plants to regulate formaldehyde concentrations, and experiments with trees have suggested that many species are tolerant of high concentrations (microlitre/litre or ppm) on short-term (hours) exposure. See review by Cape(2003).

Additional Comments:

There are no routine measurements of formaldehyde or alcohol concentrations in air in the UK.
